Characters in general as above given for Acc'qnter; size superior, and organization more robust; feet stronger, the tarsus featliered about i way down in front and on the sides, leaving only a narrow bare strip beliind ; the scutellation discontinuous at the bases of tlie toes, which are finely reticulate; resumed beyond ; never fused. These " goose-hawks " or " star-hawks" are a small genus of five or six " ignoble " species, held in high estimation by falconers for their prowess in the chase. Ours appears to be quite distinct from A. jxdumlarius, tliougli closely related. 400. A. atrieapil'lus. (Lat. atricajnllus, black-haired. Fig. 371.) Ameuican Goshawk. Ulle Hkn Hawk (adult).

Ground color of under parts, including lining of wings, white, closely barred or vermiculatcd in narrow zigzag lines with slaty-brown, except on throat and crissum, and everywhere sharply pencilled with blackish shaft-lines, one on eacli featlier.
